I have had this phone for about 6 months and did NOT do the upgrade. All of the sudden the battery wont last more than 3-4 hours on a full charge. It also gets warm like it is running something while it is not in use. This just started today and I dont see any thing obvious on the settings that I am missing. I am not very computer smart but I havent changed anything. Any body else have this problem? I did do a search here before posting this which turned up nothing.
